Family law methodology

How is Alimony Calculated in Florida?

Alimony — also called spousal support or maintenance — is the payment one spouse makes to the other after divorce to close the gap between two households. Florida does not follow a single American rule: it sets its own standard under Fla. Stat. § 61.08 (2023), and this page applies the state’s statutory approach rather than a national average.

In Florida, spousal support is decided under a statutory standard — not a one-size-fits-all national formula. Lawmakers wrote the percentages, the caps and the duration tables straight into the code, so couples with similar incomes and a similar-length marriage usually end up with similar numbers. That is exactly what the estimator on this page encodes, and it is why two states can return very different answers to the same income and marriage facts.

Statutory formulaFla. Stat. § 61.08 (2023)

Florida applies a strict mathematical guideline.

Florida’s 2023 reform (effective July 1, 2023) abolished permanent periodic alimony and fixed a mathematical ceiling: durational alimony may not exceed the lesser of the obligee’s reasonable need or 35% of the difference between the parties’ net incomes. Term caps are 50% of the marriage under 10 years, 60% for 10–20 years, and 75% for 20+ years.

Because Florida uses a formula, this calculator returns a precise point estimate or statutory band rather than a judgment call. The exact arithmetic is shown in the step-by-step math drawer of the calculator above.

Duration: Fla. Stat. § 61.08(8)(b): durational alimony may not exceed 50% of a short-term (under 10 years), 60% of a moderate-term (10–20 years), or 75% of a long-term (20+ years) marriage, and may not be awarded for marriages of 3 years or less.

What courts weigh

One factor shapes the rest: child support is worked out first in most states, so it changes how much income is left over for spousal support. That is why this child support and alimony calculator includes a children toggle — switch it on and the estimate drops in the states whose formula accounts for child support.

Standard of living

The lifestyle the couple established during the marriage.

Income & earning capacity

Each spouse's current earnings, employability, and future potential.

Length of the marriage

Longer marriages support larger and longer-lasting awards.

Age & health

Both spouses' physical condition and realistic work horizon.

Contributions

Career sacrifices, homemaking, and support for the other’s education.

Children & custody

Child support is calculated separately and often lowers the income available for alimony.

Property division

The marital estate awarded to each spouse at divorce.

Tax treatment

Post-2018 TCJA rules: alimony is neither deductible nor taxable.

Example calculation

A standard income-disparity scenario

A 12-year marriage where the payer earns $120,000 and the recipient earns $40,000, with no children — calculated with Florida’s actual rule:

Payer gross income$120,000 / yr

Recipient gross income$40,000 / yr

Length of marriage12 years

Children involvedNo

Estimated monthly payment$1,750 / month

Estimated duration86 months (7.2 years)

How the number was derived

• The Law: Florida’s 2023 alimony statute (Fla. Stat. § 61.08(8)(c)) sets the award at the lesser of the obligee’s reasonable need or 35% of the difference between the parties’ net incomes; permanent periodic alimony was abolished effective July 1, 2023. • The Math: Net income is estimated at 75% of gross (payer $7,500/mo, recipient $2,500/mo); 35% × $5,000 = $1,750/month. • Tax Impact: No TCJA adjustment or child-support modifier applies to this calculation. • Duration: Florida caps the term at 60% of the marriage for this length — giving 86 months for a 12-year marriage. Permanent periodic alimony no longer exists.

Settlement planning

Lump-Sum Alimony Buyouts & Post-Support Cash Flow in Florida

Most Florida support awards are agreed as a set of monthly payments — but the same money can be settled in one payment up front. That trade is called an alimony buyout: instead of writing a check every month for years, the payer hands over a single lump sum today, often by letting the recipient keep more of the house or more of a retirement account, so both spouses can move on cleanly. Florida’s own amount and duration rules (Fla. Stat. § 61.08 (2023)) set how much is paid each month and for how long, and that monthly stream is the thing being bought out.

Why is one payment today worth less than adding up every future check? Because money in hand now can sit in a safe account and earn interest over the same years those checks would have arrived. This alimony buyout calculator shows the same payment stream at 3.5%, 4.5% and 6.0% — the higher the rate, the smaller today’s lump sum, and the wider the gap between “paid monthly” and “paid up front”. Taking the deal up front means accepting a lump sum spousal support payment today instead of years of monthly checks.

In the 12-year, $120,000 payer / $40,000 recipient scenario used above, the monthly checks add up to $150,500 over 86 months — but settled as one single payment today they are worth $128,439 at 4.5%, $132,938 at 3.5% or $122,078 at 6.0%. That difference is what a settlement is really negotiating: the payer pays less in total, and the recipient gets the money sooner.

After the estimated $1,750-per-month transfer, the payer keeps about $5,750 per month (57% of the combined post-transfer total) and the recipient has about $4,250 (43%). The question after support is the simple one: what does each household actually have left to live on? The take-home split shows both sides after estimated taxes and after the payment, and since 2019 alimony is neither taxable for the receiver nor deductible for the payer, every dollar moves across unchanged. Print the calculator above as a spousal support worksheet and the inputs, the step-by-step math and these settlement figures all come out together on one clean page.

FAQ

Frequently asked questions about alimony in Florida

Is there a minimum marriage length before alimony is available in Florida?

Some states set a hard eligibility floor before periodic maintenance can be ordered, while others allow support after any marriage where need and ability to pay are shown. Enter your marriage length in the calculator: where Florida sets a statutory floor below your marriage length, the estimate returns $0 instead of a payment term.

Does alimony end automatically when the payer retires in Florida?

Retirement is the start of a modification request, not an automatic end. Courts look at whether the retirement is voluntary or age-driven, what assets and retirement income the payer holds, and whether the recipient still needs support — and the existing order keeps running at its current amount until a court changes it. In Florida, good-faith retirement at normal working age can justify a reduction or termination, but simply stopping payment is contempt, not a strategy.

How does Florida handle a spouse who hides income to lower alimony?

Income is measured by what a spouse could earn, not only what they report. A Florida judge may impute income based on earning capacity, employment history, and the lifestyle the marriage supported, and can compel records through discovery — subpoenas, depositions, and, in bigger cases, a forensic accountant. Understating income before or during the divorce rarely produces a lasting reduction in support.

Can Florida alimony be paid as a lump sum instead of monthly payments?

Sometimes. Some states allow a lump-sum or buy-out that converts future payments into a single present-value payment, which ends the court’s ongoing jurisdiction and removes any future modification fight. Whether Florida permits it, how the lump sum is discounted, and how it is taxed all depend on the statute and the payer’s ability to pre-fund the obligation — model both structures with your attorney before trading monthly security for a lump sum.

What proof does the Florida court need to reduce alimony for cohabitation?

Evidence of economics, not romance. Courts want to see that the household actually shares costs: a joint lease or deed, combined utility and grocery payments, commingled accounts, or contributions from the new partner that reduce the recipient’s living expenses. Florida judges also weigh how long the arrangement has lasted and whether the couple holds itself out as a partnership. Keep documentation and file a motion to modify — support continues at the current amount until the court orders a change.

Does Social Security or disability income count toward alimony in Florida?

It counts as income in most analyses — Social Security retirement or disability benefits, veterans benefits, pensions, and investment income all factor into a spouse’s resources and ability to pay. What changes is what that income can sustain: where benefits are the payer’s only realistic source, need is weighed against actual capacity rather than earning potential. Enter the real annual figure for Florida; imputation applies to income a spouse could earn, not income they no longer can.
